Invincible Summer is, in the author's words, "a autobiographical comic zine, more or less. Stories about dogs, dates, diaries and coffee. It has a definite vegan stance, and is incidentally queer". The zine also includes writing and illustration.

In the past nine years, Nicole has teamed up with Clutch McBastard and his zine Clutch for an annual split zine that features the work of both cartoonists.

Selections from Invincible Summer were reprinted in volume nine of Zine Yearbook. published in 2008.
